Physics First Semester Exam Review Part 1

Practice for the Final Exam

No grade for this. However you should keep a pencil and paper nearby to record topics that you will need help with. Plan to ask those questions between now and the exam.

What safety precautions should be take where an open flame exists in the laboratory. Check all that apply.

Long hair should be tied back.

Loose clothing should be restrained -- sleeves rolled up etc.

Flammable materials such as paper and chemicals moved away.

Open containers of volatile, flammable liquids removed from the room.

What safety precautions should be observed when small projectiles are launched in the laboratory? Check all that apply.

Eye protection should be worn.

Projectiles should be launched at an area designated as off limits to people.

Projectiles should be launched during a time when all room occupants have had the launch called to their attention.

If a dangerous chemical is spilled in the lab you should . . .? Check all that apply.

Inform the instructor immediately and follow his/her instructions.

Proceed with cleaning up the spill.

Pour a neutralizing chemical on the spill.
